Drawing on such esoteric concepts as Ilya Prigogine's chaos theory, non-Euclidian geometry, and the behavior of hyper-complex systems, Gustavo Díaz uses diverse media to create artworks that reflect his education in art, music, and science. Before deciding to dedicate himself fully to art making, Díaz studied at the Escuela Técnica Otto Krause and at the Instituto Nacional de Tecnología Industrial in his native Argentina. This background, as well as his continued studies in mathematics, philosophy, and other fields, inform the intricate lines and complex structures of his drawings, acrylic sculptures, and reliefs.

In 2001, Díaz received the Banco Ciudad Foundation Prize from the Museo Nacional de Bellas Artes, Buenos Aires, and in 2002 he co-founded NOUS, a Center of Art and Design dedicated to interdisciplinary scientific research. In 2013, the artist's work was featured at ExpoChicago, where he was named Artforum's “Critics' Pick.” Two years later, the Museum of Fine Arts, Houston included Díaz's work in an exhibition entitled Cosmic Dialogues: Selections from the Latin American Collection, which focused on artistic explorations of space and light. The show was curated by Mari Carmen Ramírez, MFAH Wortham Curator of Latin American Art and Director of the International Center for Arts of the Americas (ICAA).

Díaz's work has been shown in both group and solo exhibitions at the Museum of Fine Arts, Houston (MFAH), TX; the Museo Valenciano de la Ilustración y la Modernidad in Valencia, Spain; as well as other exhibition spaces throughout the United States and Argentina.
